The demolition seems to be nearly done on second floor. The floor quivered when they broke up the walls under my office, but I see only about 10 feet of block wall left. (So why the jackhammer this morning?)

The cast wall is turning out to be problematic: plans call for it to be ripped out, but it turns out that wall supports an exterior wall for floors 3-6. I was under the impression that architects were paid the big bucks for paying attention to details like that, but perhaps I was misled.
